Method and Apparatus for Transmitting/Receiving System Information in Broadband Wireless Communication System

1. A method of a user equipment which receives System Information (SI) of a femto base station in a wireless communication system, the method comprising: transmitting, by the user equipment, unique identification information of at least one femto base station included in a Closed Subscriber Group (CSG) to a macro base station for generating at least one measurement gap pattern representing a periodically recurring SI transmission point of the at least one femto base station in the macro base station; generating, by the user equipment, the at least one measurement gap pattern representing a periodically recurring SI reception point, wherein the measurement gap pattern is determined based on unique identification information of the macro base station and the unique identification information of the at least one femto base station, by the user equipment; and receiving, by the user equipment, the SI from the at least one femto base station according to the generated at least one measurement gap pattern, wherein the user equipment transmits the unique identification information of at least one femto base station to macro base station before detecting the at least one femto base station according to the at least one measurement gap pattern.

2. The method of claim 1 , wherein the generating of the at least one measurement gap pattern by the user equipment comprises: determining an SI transmission frame index of the at least one femto base station using the unique identification information of the macro base station and the unique identification information of the at least one femto base station; and generating the at least one measurement gap pattern based on the determined transmission frame index, wherein the user equipment and the macro base station independently determine the measurement gap pattern.

4. The method of claim 1 , wherein the user equipment stores a list comprising the unique identification information of the at least femto base station included in the CSG, and unique identification information of at least one macro base station with which the least one femto base station is associated.

5. An apparatus of a user equipment which receives System Information (SI) of a femto base station in a wireless communication system, the user equipment comprising the apparatus, the apparatus comprising: a transmitter for transmitting unique identification information of at least one femto base station included in a Closed Subscriber Group (CSG) to a macro base station for generating at least one measurement gap representing a periodically recurring SI transmission point of the at least one femto base station in the macro base station; a memory for storing the unique identification information; a measurement gap pattern generator for generating the at least one measurement gap pattern representing a periodically recurring SI reception point, wherein the measurement gap pattern is determined based on unique identification information of the macro base station and the unique identification information of the at least one femto base station by the measurement gap pattern generator of the user equipment; and a receiver for receiving the SI from the at least one femto base station according to the generated at least one measurement gap pattern, wherein the user equipment transmits the unique identification information of at least one femto base station to macro base station before detecting the at least one femto base station according to the at least one measurement gap pattern.

6. The apparatus of claim 5 , wherein the measurement gap pattern generator determines an SI transmission frame index of the at least one femto base station using the unique identification information of the macro base station and the unique identification information of the at least one femto base station, and generates the measurement gap pattern based on the determined transmission frame index, wherein the user equipment and the macro base station independently determine the measurement gap pattern.

8. The apparatus of claim 5 , further comprising a storing unit for storing a list comprising the unique identification information of the at least one femto base station, and unique identification information of at least one macro base station with which the least one femto base station is associated.
